[AccessD] Comparing date and time

David,

If the [Date] and [Time] fields in the table are a Date/Time data type, 
and if the criteria controls on the form are formatted with a valid date 
and/or time format, then I don't think you would need the CDate and 
DateValue functions as you have used them.  I would expect (without 
having tested) that this would work:
"WHERE (EntryLogSets.Date + EntryLogSets.Time) Between (#" & 
[Forms]![BSVR]![BsvrStartDate] & "# + #" &
[Forms]![BSVR]![BSVRStartTime] & "#) And (#" & 
[Forms]![BSVR]![BsvrEndDate] "# + #" & [Forms]![BSVR]![BSVREndTime] & "#)"

I always wrap date and time criteria in CLng or CDbl to handle 
international problem, so I would do it like this:
"WHERE (EntryLogSets.Date + EntryLogSets.Time) Between (" & 
CLng([Forms]![BSVR]![BsvrStartDate]) + 
CDbl([Forms]![BSVR]![BSVRStartTime]) & ") And (" & 
CLng([Forms]![BSVR]![BsvrEndDate]) + CDbl([Forms]![BSVR]![BSVREndTime]) 
& ")"

Regards
Steve
